In a cross-sectional structure of an existing blade rubber having a non-hollow cross-section, only elasticity of a material of the blade rubber is used for pressure to wipe a windshield. Therefore, it is difficult for the blade rubber to flexibly follow change of a surface shape of the windshield, and sufficient wiping performance is not obtainable. A blade rubber to be attached to a frame of a vehicle wiper and to wipe the windshield according to the present invention includes a wing portion extending in a lateral direction to fix the blade rubber to the frame, a neck portion perpendicularly coupled to the wing portion, a deformation portion elastically deformable and coupled to a lower side of the neck portion, and a contact portion provided on a side of the deformation portion opposite to a side provided with the neck portion, and configured to abut on the windshield. The deformation portion internally includes a cavity portion having a heart-shaped cross-section. The neck portion is coupled to an upper intersection of two curved portions surrounded by an outside of the deformation portion and the heart-shaped cavity. The contact portion is coupled to a lower intersection.

The invention relates to a wiping device, in particular a wiping device for a motor vehicle pane, comprising a spoiler unit (22a-22p). According to the invention, said spoiler unit (22a-22p) is produced in a co-extrusion process.

A wiper blade including an elongate wiper strip, an elastic backing element and a mounting base. The wiper strip including a lip, a wide portion, and narrower intermediate portion between the lip and the wide portion. The backing element having a top portion from which two legs descend, such that each leg includes a claw that extends towards the opposite leg and has ends that define a gap sized to receive the intermediate portion of the wiper strip. The top portion, legs and claws of defining a wiper strip cavity where the wide portion of the wiper strip is disposed. The mounting base disposed on a section of the backing element and capable of connecting the wiper blade to a wiper arm and receiving force from same, such that the mounting base applies the force from the wiper arm to the backing element, which distributes same along the wiper strip.
